26 and the passage "22 i.

'By means of the passages 22, 28 and 24, com- '13. A pipe 29 is inserted in a neck 26 formed on the cover 13 of the float chamber 13. The neck '26 is screw-thread.ed to re ceive a cap 27, having air inlet passages 28. The tube 29 is inserted in the neck 26- and communication with. the outer air is established by means of the passages 28, the tube which any may be admitted can be regulated by the adjustment of .the cap 27 with reference to the upper end of the tube 29. The spring 30 for the purpose .oftaking up the back lash or free movement of the cap upon the threads on'th e neck 26. The passage '23 is Constructed of approximately the Theamount of air Lea ers 3. A carburetor comprising acarbureting discharging into said carbureting chamber and also having jetting ports in one of its other walls, said latter ports being coaxial with the ports in the side wall and said other wall being spaced from the side wall to iorm an annular fuel sump and a member having a fuel. discharge port' discharging into the chamber in the suction controlled valve.

4. A carbureter comprising in combination a tubular member having a multiplicity of air supply ports, a piston valve for controlling said ports, a chamber in said piston valve, a member having a fuel discharge port discharging into said chamber in said same diameteras each oi the passages 28, PIStOII V1llVe, (llSCllL1g ports in the walls of of which there are a multiplicity, usually the passages 24, 23, and the tube 22, thereby'somewhat reducing the head which acts to force the liquid fuel from the float chamher into the carburetor.

31 is a pointersecured in position. by the nut 32. By the regulation of the cap 27 the ratio between thefuel and the air admitted to the carbureter may be varied.

Having described my invention I claim 1. "A carbureter comprising in combination a suction-controlled valve adapted to regulate the flow of air to the carbureting chamber, a chamber in said valve, a member having a fuel discharge port discharging into'said chamber in said valve, ports in the I sidewall of said. valve in open communication betweel'i said carbureting chamber and said chamber insaid valve, and ports ror admitting air to said chamber in said valve,

said last mentioned ports being arranged .to discharge air jets through. said first mentioned ports into the carbureting chamber. 2. A carburetor comprising a carbureting chamber, a suction controlledvalve adapted to regulate the flow of: air to the carbureting chamber, a chamber in said valve, a mom-- 'ber havinga fuel discharge port dischargiug into tne chamber in said valve, a narrow annular sump in the bottom of the chamber in said valve adapted to collect the fuel discharge intosaid chamber, ports in open communication between said carbureting chamber and the chamber in said valve and ports arranged to discharge air jets across said sump and through. said first mentioned ports into said carbureting chamber.

,means for supplying air to the chamber in the piston valve.

5. A carburetor comprising in combina tion a tubular member having a multiplicity of air supply ports, a pistonvalve for controlling said ports, a chamber in said piston valve, member having aifuel discharge port discharging into said chamber in said piston valve, a multiplicity of discharge ports in the walls of said chamber in said piston valve registering with the ports in the-tubular member, and a multiplicity'of air .supplyports leading into said chamber in the piston valve and registering with said discharge ports in said piston. valve.

6. A carbureter comprising in combine tion. atubular member having a multiplicity of airsupply ports, a piston valve for 0011-. trolling said ports, a chamber in said piston valve, a member having a fuel discharge port discharging intov said chamber in'said piston valve, a multiplicity of discharge ports in the walls of said chamber in. said piston val ge registering with said ports insaid tubular member, and a multiplicity of air supply ports leading into said chamber in said piston valve and registering with said discharge ports in said piston valve, but of smaller bore than said discharge ports in said piston. valve.
